`File this under “what’s old is new again.” A German company is introducing sails it says may help propel ships across the sea cheaper and faster than modern engines.
SkySails’ system consists of an enormous towing kite and navigation software that can map the best route between two points for maximum wind efficiency. In development for more than four years, the system costs from roughly $380,000 to $3.2 million, depending on the size of the ship it’s pulling. SkySails claims it will save one third of fuel costs.’
